This European Standard establishes safety requirements for food depositors. This group of machines is defined in detail in clause 3.2 of this standard, with diagrams illustrating examples of the principle of operation of each machine type.

This standard covers the safety requirements for machine design, construction, installation, commissioning, operation, adjustment, maintenance and cleaning. This standard applies to machines manufactured after the date of issue of this standard.

NOTE Although this standard is primarily intended to apply to depositors used in the food industry, it should also be noted that the same machines are also used to deposit non-food products. Where depositors are used for non-food products, the health and safety requirements of this standard will apply, but the hygiene requirements will not apply.

Exclusions

This standard is not applicable to the following machines:

- Auger depositors or auger fillers and gravimetric filling machines; safety requirements for these machines are contained in EN 415-3:2000.

- Food depositors that are powered exclusively by manual effort;

 - Food depositors that were manufactured before the date of publication of this document by CEN;

This standard does not consider the following hazards:

- the use of food depositors in potentially explosive atmospheres;

- the health, safety or hygiene hazards associated with the products that may be handled by the machines,-but does include general advice on this subject;

 -hazards that may be associated with electromagnetic emissions from food depositors;

 -hazards that may be associated with decommissioning food depositors.
